INVENTOR. O'r'ro \IJ. SCHWEJKLE n teds tc Pa n ce TROUBLE LAMP Otto W.Schweikle, Williamsport, Pa. Application June 14, 1957, Serial No.665,684 3 Claims. (01. 240-54 The present invention relates toelectrical illuminating means, and more specifically, the presentinvention pertains to a guard for an electric light bulb.

One of the primary objects of this invention is to provide a handlemounted electric light bulb with a guard or shield which may be adjustedto permit the passage therethrough of greater or lesser amounts of lightrays.

A further object of this invention is to provide a trouble lamp with animproved combination of a light guard and reflector means.

It is a still further object of this invention to provide a trouble lampwith a light guard and reflector, the reflector being adjustable tocontrol the light ray emission.

This invention contemplates, as a still further object, the provision ofa trouble lamp of the type referred to above which is noncomplex inconstruction and assembly, inexpensive to manufacture, and which isdurable in use.

Other and further objects and advantages of this invention will becomemore apparent from a consideration of the following specification whenread in conjunction with the annexed drawing, in which:

Figure 1 is a perspective view of a trouble lamp constructed inaccordance with the teachings of the present invention;

Figure 2 is an enlarged detailed cross sectional View, partly inelevation, the view being taken on the vertical plane of line 22 ofFigure 1, looking in the direction of the arrows;

Figure 3 is a detailed cross sectional view taken on the horizontalplane of line 33 of Figure 2, looking in the direction of the arrows;

Figure 4 is a detailed cross sectional view taken on the horizontalplane of line 4-4 of Figure 2, looking in the direction of the arrows;and

Figure 5 is an exploded perspective view of the lamp guard and reflectorunit.

Referring now more specifically to the drawing, reference numeral 10designates, in general, a trouble lamp constructed in accordance withthe present invention. The lamp 10 is seen to include an elongatedsubstantially hollow cylindrical handle 12 having an electric lightsocket 14 fixedly secured to one end thereof. One end of an electriclight cord 16 is extended through the hollow handle 12 and connected tothe socket 14 in the conventional manner. A conventional push buttonswitch 18 controls the flow of current to the socket 14. As isillustrated in Figures 1 and 2, the socket 14 receives a conventionallight bulb 20.

The combined lamp guard and reflector device to which the presentinvention is addressed is designated, in general, by the referencenumeral 22. This device is seen to include a substantiallyfrusto-conical support member 24 which terminates at its lower end in adepending hollow cylindrical split collar 26, the ends of whichterminate in laterally and outwardly turned confronting tabs 28, 30. Thecollar 26 surrounds and engages the socket 14 and the support member 24is rigidly se- Patented Nov. 18, 19 58 cured thereto by means of thescrew 32 which extends through suitable apertures formed in the tabs 28,30 and the lock nut 34. The support is completed by providingv aplurality of circumferentially spaced apertures 36 at the junction pointof the collar with the support member 24.

The upper end of the support member 24 terminates in a flange 38 whichis reverted over a reverted flange 40 formed on the lower end of avertically elongated substantially hollow cylindrical member 42. Theupper end of the member'42 terminates in a reverted flange 44 in orderto lend rigidity to the structure and to present a blunt edge. Themember 42 is provided with a semicircular opening or window 46 havingvertically spaced and substantially parallel top and bottom flanges 48,50, respectively. At vertically spaced intervals, the opening 46 istraversed by a plurality of substantially semi-circular ribs 52 fixedlysecured to the member 42 adjacent the marginal sides of the opening 46.At radially spaced intervals, the opening 46 is traversed in a verticaldirection by a plurality of outwardly bowed lips 54 having their opposedends rigidly secured to the flanges 48, 50.

Reference numeral 56 designates, in general, a reflector for the troublelamp 10. The reflector 56 is seen to comprise a vertically elongatedsubstantially hollow cylindrical element 58 having a semi-circularopening 60 formed therein. Reference numerals62, 64 denote a pair ofvertically spaced and substantially parallel flanges at the upper end ofthe opening 60, the flanges being.

separated from each other by a semi-circular slot 66. As is clearly seenin Figures 2 and 5 of the drawing, the

flange 64 is interrupted by a vertically extending slot 68 v whichcommunicates with the slot 66 at its upper end. A flange 70 is disposedat the lower end of the opening 60, the flange 70 being coaxiallyaligned with the flanges 62, 64. The flange 70 is traversed by a groove72 that is disposed in vertical alignment with the slot 68.

The cylindrical element 58 is telescoped within the cylindrical member42, the grooved portion 72 passing a locking pin 74 which projectsinwardly from one end of the flange 48. The pin 74 enters the slot 68formed.

opening 78 is rigidly secured to the upper end of the cylindricalelement 58 by conventional means. Reference numeral 80 designates, ingeneral, a plurality of struts. Each of the struts 80 is substantiallyL-shaped in configuration and includes a foot portion 82 fixedly securedto the annular member 76 at radially spaced intervals. The leg portions84 of the strut 80 converge at an angle upwardly and the upper endsthereof are bent vertically to provide terminal ends 86. The ends 86 arefixedly secured to the lower end of a stem 88 of a substantiallyC-shaped hook 90.

With the reflector 58 disposed within the guard 42 in the mannerdescribed above, it now becomes obvious that the operator may controlthe degree of light emanating from the bulb 20. Through the simpleexpedient of turning the reflector 58 by the leg portions 84 or hook 90axially Within the guard 42, or by holding the hook stationary androtating the handle 12, the reflector 58 may be extended across agreater or lesser area of the opening or window 46 formed in the guard42. The present invention embodies the guard with the adjustable featurewhich allows light to emanate from the side or if the side opening isclosed entirely, then all the light rays will emanate from the open endof the device.
